Image processing device and image processing method
Abstract
The present disclosure relates to an image processing device and an image processing method that enable image processing to be performed with a smaller number of line buffers. The image processing device includes a decoding unit that decodes a bitstream to generate an image according to an encoding standard in which a horizontal size of one tile is restricted for each level by a restriction value. The restriction value is set according to a maximum value MaxLumaPs of the number of luminance picture samples, and also restricts a vertical size of one tile. The present technology can be applied to, for example, an image processing system that performs encoding and decoding according to the VVC method.
Claims
exact text as granted — not AI-modified1 . An image processing device comprising:
processing circuitry configured to transmit a bitstream generated by encoding according to an encoding standard in which a horizontal size of one tile is restricted by a restriction value, wherein the restriction value is enabled by a flag in the bitstream, wherein the restriction value is set according to each level that defines maximum resolution and frame rate and the following equation (1) using a maximum value MaxLumaPs of the number of luminance picture samples
